JNI 64bit JVM, load 32bit native library

[mark.faine]

Is it possible to load a 32bit native library (linux.so) using a 64bit
version of Java?

Thanks,

If this is not possible, which at this point, I believe it is not. How
do I build a 32 bit version of JSVC on AMD_64 Linux?

Thanks,

I've never tried to mix sizes, so this is just an idea on general
principles.

Have you considered writing a 64 bit wrapper library, in e.g. C, that
interfaces to the 32 bit native library?

I'm pretty sure you cannot mix 32bit and 64bit binaries, they will not co-exist.

It is possible to run 32bit executables on a 64it platform, however. If the
platform is AMD64 or EMT64 then it should cause no problems at all. All you
would need is to install a 32bit JRE.

On running "mvn exec:exec" I am getting following error

64-bit Java Virtual Machine to load

32-bit native libraries.
